Weird Impulse Response

Dear all,

My problem is that the impulse response of interest shock looks quite weird in the sense that some impulse responses figures have two Inflection points. Is this a timing problem?

Hope someone can give a hint.

Thanks.

Unless you are dealing with news shocks or permanent technology shocks, it is most likely a timing issue.
